This invention relates to a surgical operating'support and moreparticularly to a folding portable bed or operatlng table esj; peciallyuseful in connection with obstetrical cases.

7. made as to prevent complete sterilization and also some are soconstructed as to be cumbersome when utilized as a portable device.

An object of the present invention is to provide a light, readilyportable simple, yet

7 rigid, obstetrical table or support which is 5 comfortable for apatient'and which may be kept clean and sanitary.

A further objectof the invention is to provide a portable obstetrical orsurgical bed which may be placed upon the dressings of an ordinary bedwith the patient lengthwise of the bed in a normal position, but uponwhich she can be turned crosswise of the bed for operative measures, andthe desired positions secured without moving the equipment on the bed ordisturbing the'drainage or dressings. It is often vitally important thatthis change in position be accomplished quickly and with minimum effort.Heretofore no such equipment has been provided with adequate adjustmentsfor such change.

Another object of the invention is to provide an obstetrical'table withknee rests and standards for supporting the knee rests in any position,-which rests and standards may be readily adjusted and also separated forpacking in small compass for ready portability.

Another ObJGCt Of the invention is to provide knee rests for use withobstetrical tables and the like, which rests are hinged or jointed forangular adjustment about the hinges for the purpose of greater comfortto the pa.- tient, and also for the purpose of allowing packing of thesame in a more compact com.- pass than possible with the present type ofknee rests.

Another object 'of the invention is to provide standards for the kneerests which standards have offset ends whereby greater lateraladjustment of the knee rests is secured inwardly and outwardly of theside margins of the table. i

A further object of the invention is to provide a foldable portable allmetal obstetrlcal bed or table having knee rests and standards forsupporting the rests, which bed is foldableinto compact form and inwhich may be stowed the knee rests. and

standards and which also is provided with a i portable electric light,one terminal of which may be connected to a battery within the bed andanother terminal of which may be attached to any part ofthe bed,'kneerests, or standards for closing circuit through the light, whereby thesame may housed in any position about, aboveor around the structure.

A still further objectof'this'invention is to provide a foldable,portable, obstetrical bed withknee rests and standards forthe support ofthe rests, all of which may be packed in compact relation within thecompass of an ordinary suitcase for ready portability.

The above, other and further objects of the invention will be apparentfrom the following description, accompanying drawings and appendedclaims. i

An embodiment of the invention is illustrated in the accompanyingdrawings and the views thereof are as follows:

Figure 1 is a top plan view of an obstet-' rical bed embodying thepresent invention and showing the bed in opened position with the kneerests and standards for the same in,

Figure 3 is a bottom plan view of the il- I knee rest standards with theparts in variously adjusted position.

Figure 5 is a perspective view of a case with a port-ion broken awayshowing parts of the illustrated form of the invention in folded andpacked relation.

Figure 6 is an elevational view of one kind of electric light supporthaving a flexible neck.

Figure 7 is a view similar to Figure 6 taken at 90 with respect toFigure 6.

The drawin s will now be explained.

The form bed or support chosen to exemplify the present inventionincludes two hi ed metal sections A and B which are [h2 8 preferably ofcast aluminum, so as to be light, rigid, and readily sterilized. Thesections A and B are hinged together by means of hinge pins 1 whichextends through ears 2 of the section A and adjacent apertured portions3 of the section B.

The section A is shown as provided on its underside with a flange 4extending about three of the margins of the underside of the section orleaf, while the underside of the section B is shown as having a flange 5extending about the four sides of the same, which flange is thickened atthe parts 3 for receiving the pivot pins 1,. The flanges 4 and 5 serveas means for preventing movement of the bed or table when the same isopened on any convenient support, such as on the bedding of an ordinarybed or on a table or other place where the surgical support of theinvention may be used.

The undersides of the outer corners 6 and 7 of the leaf A and corners 8and 9 of the leaf B are thickened and provided with openings 10 througheach one of the thickened corners, which openings are substantiallycircular for a greater portion of the length of the same and whichopenings have lateral cutouts 11 for a purpose to be later explained.

An electric battery C is removably supported on the lower side of one ofthe leaves of the bed. The battery C is shown secured to the undersideof the leaf B by means of a cli 12, another clip 13 with the latter ofwhic is associated a flange 14 to receive a sprin 15 between it and oneend of the battery The spring 15 serves as aconnection between thebattery and the metal leaves of the table. A jack opening 16 is providedad- 'acent the other end of the battery for receivmg one end 17 of aplug connector attached to the positive terminal conductor 18 of aportable light.

The depth of the flanges 4 and 5 on the undersides of the leaves A and Bis such as to receive the battery C and also to contain the kneesupports and knee support standards and the light and hand and legstraps used with a table of this sort when the same is folded forportability.

A pair of knee support standards E and F are provided, each of which hasa cylindrical end 19 for entering one of the openings 10 through thecorners of the leaves and which end 19 is provided with a laterallyextending pin 20 for entering the recess 11 and on rotating of thestandards will lock the same against accidental vertical displacement.The standard immediately above engagement with the table leaf is offsetlaterally as at 21 and then is turned upwardly providing a verticalportion 22. Either of the standards E or F may be inserted in any of thefour corners of the table so that as the patient may be moved from oneposition to another, the knee rest standards may be adjusted withoutinconvenience to the patient.

The provision of the lateral offset portion 21 in the standards allows agreater degree of lateral adjustment of the knee rests than is possiblewith the present form of standards, which are vertical. without any suchoffset portions.

Furthermore, the provision of the lateral offset portion 21 of thestandards E and F enables the spreading of the knee rests to a greaterdistance than that of the width of the table, thus enabling the use of atable which when folded may be readily portable.

Knee rests G and H are provided, made preferably of aluminum and eachconsists of two portions 23 and 24 which are hinged at 25. Each of theportions 23 and 24 is con cave on its inner side so as to receive a kneeof a patient and support the same comfortably. The hinging of theportions 23 and 24: allows relative angular adjustment should a casearise for increasing comfort in supporting a patients knees. Each of theknee rests is provided on the portion 23 with a lateral lug 26 having anaperture 27 therethrough inclined with respect to the surface of theportion 23 for receiving one of the standards E or F. The rests aresecured in vertical adjustment on the standards by set screws 28.

The rests G and H are vertically and angularly adjustable on thestandards E and F and also the standards E and F are angularlyadjustable with respect to the points of support of the same in thetable so that a patient may be comfortably supported on the same. Eachof the standards E and F is provided with a sliding block 30 which isadjusted vertically on the portion 22 of the same by means of a setscrew 31. The block carries a leg strap 32 which may be adjusted aboutthe'legs of a patient when the same are on the knee rests G and H, whereit is necessary to strap the legs to the rests.

Hand straps 33 are attached to rings 34- which surround the lower end 19of the standards E and F adjacent the upper surface of the sections Aand B when extended. The oflset portions 21 of the standards preventupward movement of the rings 34 when pressure is applied thereto by thepatient.

A portable light K is provided with a metallic end portion 34 having abifurcated lower extension 35 for engaging over a thumb screw 36 whichmay be threaded into a threaded opening in flanges of the section A forremovably securing the light K to the table. The light K includes aflexible gooseneck 37 which carries at its free end the bulb 38 which isprotected by a hood and reflector 39 so as to direct the light rays inone direction. The positive terminal 18 is provided with a connectorplug 17 for cooperating with the battery C as before described and asillustrated in Figure 3. The negative terminal 40 is provided with aspring clip 41 which may be readily attached to any part of the table,standards, or knee rests for closing circuit through the bulb 38.

The light K may be positioned on any of the screws 36 as abovedescribed, or may be engaged over one of the set screws 28 whichadjustably secure the knee rests G and H on the standards E and F. Theend portion 34 is grounded so that as soon as any metallic portion ofthe table and accessories is touched by the end portion 3% the bulb 38will light even though the negative terminal clip 41 is 7 not engaged.Should it be desired to use the .to allow considerable light forexploratory examination, then it may be removed from the screw 36 andthe negative clip terminal 41 engaged on any part of the metallicstructure whereupon the bulb 38 will light and the same may be used forexploratory purposes, the terminals 18 and 10, of course, being ofsufiicient length movement of the light K.

Figures 1 through 4 show the table opened and with the accessoriesattached thereto for use in an obstetrical case or surgical purposes orfor examination purposes.

Figure 5 illustrates the sections A and B folded and inserted in acontainer L which is similar to an ordinary suit case and shows indotted lines the extended positions of the knee rests G and H when thesame are packed between the folded sections A and B. The standards E andF as well as the light K and the straps 32 and 33 are also packedbetween the folded sections A and B so that the structure, when folded,is compact and contains everything necessary for setting up a fullyequipped obstetrical table at the place of use.

A surgical table made in accordance with this invention may be readilycarried from place to place by the visiting physician and quickly set upfor use. All of theparts being of metal enables the table and itsaccessories to be sterilized completely and. the

straps are made of such material as to enable complete sterilization ofthe same Without destroying the same.

A surgical table made in accordance with this invention may be carriedfor out patient cases and when set up provides everything that the bestequipped in any hospital provides for such cases.

The battery C is a dry cell such as may be purchased anywhere and whenone of these becomes played out a new one may be inserted for theexhausted one.

The standards E and F, as before stated, may be rotated about the pointsof support of the same in the table to accommodate the position of theknee rests G and H to suit the comfort of the patient in accordance withthe position of the patient as desired by the physician. It will beobserved that either standard may be readily removed from any one of thecorner holes in which it is inserted and applied to any of the others,thus enabling quick adjustment of the patients body on the table shouldoccasion arise.

The invention has been described herein more or less precisely as todetails, yet it is to be understood that the invention is not to belimited thereby, as changes may be made in the arrangement andproportion of parts and equivalents may be substituted without departingfrom the spirit and scope of the invention.

The invention is claimed as follows:

1. I11 combination, a table, a standard on the table, a surgical kneesupport comprising a rigid exposed limb-joint fitting surface, and meanson a side of said support adjustably mounted on said standard foradjustable supported connection of said knee support.
